does anyone have an svn version history browser

[Rob Giardina]

working in svn i often want to see the life-story of some file i'm
working on.

i'd like to be able to walk backwards using ediff to see the diffs
between version N-1 and N, a simple additional step should then show
me the diffs between versions N-2 and N-1, etc.

http://code.google.com/p/svn-time-lapse-view/ does this out of emacs
but i'd prefer ediff.

i might waste a ton of time writing this some day soon but i'm
wondering if there's something out there that I haven't found.

thanks,
rob
